Mirror or scale an STL
Mirror makes the opposite-hand version of a part — the left bracket from the right one. Scale by a percentage, or type the width, depth or height you need and let the rest follow.

Saves model files for your slicer, never printer code. Opened and sliced in PrusaSlicer, OrcaSlicer, Bambu Studio and Cura.
Mirrored the right way out
Mirroring a model turns every triangle inside out; many quick tools leave it like that, and the slicer then reports errors. Here the surface is turned back, so the mirrored part is as solid as the original.
Scaling keeps it on the bed
The model grows or shrinks from the middle of its bottom, so it stays where it was on the bed instead of sinking below it or sliding away.
Questions
- Can I scale only one direction?
- Yes: untick “keep proportions” and type the new size for that one direction.
